What is A1N30?
A1N30 is a JIS-specific commercially pure aluminum in the 1000-series family, in a purity band comparable to 1230 and aimed at capacitor foil and other precision foil work. It is chosen for 98 formability, 90 weldability, 230 W/m-K thermal conductivity and 61% IACS electrical conductivity, and is supplied as foil and thin strip in O, F, H12 through H19 and H22 through H26. Strength is low at 30 MPa yield, 80 MPa tensile, 23 HB and 30% elongation, machinability is 25, corrosion resistance scores 72 and service is limited to 150 C. 1230 is the nearest alternative where JIS foil supply is not available. A1N30 has a density of 2.71 g/cm³ (0.0979 lb/in³), heavier than 51% of aluminum grades. It melts at 646°C (1,195 °F). A1N30 has a yield strength of 30 MPa (4.35 ksi) and a tensile strength of 80 MPa (11.6 ksi) — weaker than 97% of aluminum grades. Elongation at break is 30% and the elastic modulus is 69 GPa (10 Msi).

Working with A1N30
Is A1N30 easy to machine?
Rarely machined; very soft and gummy — use sharp polished high-rake carbide, high speed, generous lubricant, and expect burrs on any slitting or die-cutting operation.
Can A1N30 be welded?
Excellent GTAW/GMAW/ultrasonic weldability with 1100 or 1188 filler in thicker gauges; in foil gauges joining is normally ultrasonic, resistance or adhesive lamination since fusion welding burns through.
Can A1N30 be formed, bent or molded?
Outstanding cold formability in O/H22 tempers (deep-draw pouch foil); hard H18/H19 foil work-hardens fast and should be interannealed at 300–380 °C if further forming is needed.

What surface finishes work on A1N30?
Takes clear anodizing, chemical conversion (chromate-free passivation) and PET/PP/nylon lamination well; degrease and remove rolling oil before coating, and etch (DC/AC) for capacitor foil surface area.

A1N30 — frequently asked
What is A1N30 used for?
A1N30 is typically used for electrolytic capacitor foil, precision foil stock, laminated pouch and barrier foil, etched anode foil blanks, thin-gauge electrical strip and foil for heat exchanger fin stock. In short: JIS precision foil grade; 1230-class purity band; formability 98, weldability 90.
What is the yield strength of A1N30?
A1N30 has a typical yield strength of 30 MPa (4.35 ksi) and a tensile strength of 80 MPa (11.6 ksi) — weaker than 97% of aluminum grades. Strength varies by condition: see the 10 listed tempers.
Is A1N30 easy to machine?
Not especially — machinability is rated poor (25/100, worse than 96% of aluminum grades). Rarely machined; very soft and gummy — use sharp polished high-rake carbide, high speed, generous lubricant, and expect burrs on any slitting or die-cutting operation.
Can A1N30 be welded?
Yes — weldability is rated excellent (90/100). Excellent GTAW/GMAW/ultrasonic weldability with 1100 or 1188 filler in thicker gauges; in foil gauges joining is normally ultrasonic, resistance or adhesive lamination since fusion welding burns through.

What is the maximum service temperature of A1N30?
A1N30 is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between A1N30-O and A1N30-H19?
O is the default condition — default soft condition for laminate/pouch foil, deep-drawn packaging and formable foil where maximum elongation is needed. H19: maximum cold work, used for very thin high-tension foil runs and etched capacitor foil substrates. Yield strength is 30 MPa in O versus 150 MPa in H19.
How much does A1N30 cost?
A1N30 is a standard-cost aluminum ($$), cheaper than about 71% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
